Multiple Ovulation Embryo Transfer (MOET)

MOET is the more traditional method of embryo production.

The process uses hormones, primarily Follicle Stimulating Hormone (FSH), to stimulate the ovaries of cycling cattle to induce multiple ovulations. Donor cows are then inseminated (often with two straws of semen) and fertilisation of the multiple oocytes (eggs) occurs within the reproductive tract. Seven days later, embryos are flushed from the uterus and are either transferred as fresh embryos or frozen to be transferred at a later stage.

The resulting pregnancy rates using MOET technology are expected in the region of 50% or greater. At this point of time the utilization of sexed semen using MOET technology is not efficient.

The MOET donor program process is illustrated below (click image to enlarge).
